WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 320,289, dated June 16, 1885.

I Application filed December 20, 1884. (N model.)

To all whom it may concern.-

Be it known that I, Mortars Ronn'n'rs, a citizen of the United States, residing in the city and county of Philadelphia, State ot'Pennsylvania, have invented a new and useful Im provement in l/Vindow and Insect Screens,

which improvement is fully set forth in the following specification and accompanying drawings, in which Figure 1 represents a side elevation of a window or insect screen embodying my invention. Fig. 2 represents avertical section there of in line as :0, Fig. 1. Fi 3 represents a perspective View of a detatched portion enlarged.

I 5 Similar letters of reference indicate corresponding parts in the several figures.

My invent-ion consists of a window-screen formed of sliding frames having coincident kerfs or slots and clips, which latter pass through both kerfs and are secured to one frame and operate in the kerf or slot of the other frame.

It also consists of the cross-pieces of a screen, having their upper and lower faces beveled in opposite directions, forming a ridge, which provides a tight joint between the windowsash and sill whether said joint is beveled or right angular.

Referring to the drawings, A represents two frames of awindow or insect sereen,which are provided with netting usual in articles of the class. In the upper and lower pieces of each frame are slots or kerfs a, which are formed at coincident places and have passed through 5 them the clips 13, whereby said frames are connected and permitted to slide one on the other for the purposes of adjustment of the screen in the window or other place of service, and also for folding. The clips B are formed, preferably, of pieces of sheet metal, and each is bent at one end, forming lips I), which is provided at its end with spurs c, which are adapted to pierce the upper and lower pieces of the frame, thus connecting the clip therewith, it be- 4 5 ing noticed that the clips for each pair of kerfs a are connected with the respective top and lower pieces of the frames on opposite sides thereof. After the clips are passed through the kerfs a, and the spurs c driven into the wood of the frames, the ends of the clips are turned up, forming lips (I, which, as

is evident, serve in connection with the lips I) to secure the frames to each other, the lips (I being freely attached to the top and bottom pieces of the frames, whereby the frames may be moved in opposite directions, requisite for adjustment in windows, &c., and folding purposes. There is a simplificationin the construction and connection of screens of this class. Piercing of the upright pieces is avoided, and the use of wooden dowels or guides, which warp and break, is obviated. \Vhen the spurs 0 are dispensed with, the lips b may be secured directly to toe-frames by screws, nails, 850., as shown by the openings in Fig. The upper and lower faces of the top and bottom rails or cross-pieces of the frames A are beveled, it being noticed that the bevels of contiguous pieces are in reversed directions, so that vertically-project 7o ing ridges or ridge-lines exist centrally at the top and bottom of the frames, as more clearly shown in Fig. 2. By this provision the screen is adapted to be fitted to a window whether the sill and under surface of the lower rail of a sash are beveled or flat or oppositely beveled, the result being in all cases the creation of a tight joint between the screen and win- (low by contact of the sash and sill with the ridges, and the screen may be applied in position regardless of top or bottom.

I am aware that it is not new in window screens to use clips which are fastened to one frame and slide in the other, and such I do not broadly claim.

Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is-

1. A window or insect screen having sliding frames connected by clips which pass 0 through coincident slots in both frames and are rigidly secured to one frame, operating in the slot in the other, substantially as and for the purpose set forth.

2. The frames of a window or insect screen 9 5 having coincident kerfs or slots, in combition with clips passing through said slots in 4. A window-screen having the cross-pieces both frames, substantially as and for the purof the frames beveled in opposite directions, IO pose set forth. forming a ridge on said cross-pieces, substan- 3.
